Which of the following statements about moles is FALSE?SELECT AN ANSWER

One mole of carbon would contain 6.02 x 1023 carbon atoms, but one mole of chlorine would contain 6.02 x 1023 diatomic chlorine molecules.

For ionic compounds, the representative particle is the formula unit of the compound (eg. NaCl).

One mole of water (H2O) contains 6.02 x 1023 atoms.

Avogadro's number is the number of discrete, representative units found in one mole of a substance.

Answers

Answer:

Option C

Explanation:

Avogadro number represent discrete unit of a substance which can be atom, molecule, ion etc.

In one mole of H2O there will be 6.02 x 1023 molecules and not atoms.

Molecule of H2O is the discrete unit of water mole and not atom.

Hence, option C is correct choice of answer

Chemical reactions always produce explosions yes or no

Answers

not all reactions occur spontaneously. An explosion occurs when the reaction is so favorable that there is a large release of energy. An explosion can then drive more reactions.

No, they do not always produce explosions for an example baking can have a chemical reaction but you dont see my scrambled eggs explode when i make them

4-methyl-3-hexanol was prepared by reacting an alkene with either hydroboration-oxidation or oxymercuration-reduction. Draw the structure of the alkene that was used to prepare the alcohol in highest yield.

Answers

Answer:

Structure in attachment.

Explanation:

The oxymercuration-demercuration of an asymmetric alkene usually produces the Markovnikov orientation of an addition. The electrophile ⁺Hg(OAc), formed by the electrophile attack of the mercury ion, remains attached to least substituted group at the end of the double bond. This electrophile has a considerable amount of positive charge on its two carbon atoms, but there is more positive charge on the more substituted carbon atom, where it is more stable. The water attack occurs on this more electrophilic carbon, and the Markovnikov orientation occurs.

In hydroboration, borane adds to the double bond in one step. Boron is added to the less hindered and less substituted carbon, and hydrogen is added to the more substituted carbon. The electrophilic boron atom adds to the less substituted end of the double bond, positioning the positive charge (and the hydrogen atom) at the more substituted end. The result is a product with the anti-Markovnikov orientation.
